REPTILES. 



laterals ; the latter united with the loreal, and forming only one 

 shield, in contact with the second and third upper labials : as 

 this may be only accidental in the individual, I do not venture 

 to form a new genus for the species. Vertical shield elongate, 

 five-sided, with nearly parallel lateral edges and a rather obtuse 

 angle behind; occipitals rather small, pointed and divergent 

 behind ; superciliaries narrow, elongate ; anterior ocular just 

 reaching the surface of crown ; two posterior ones ; loreal none ; 

 two nasals, nostril between ; eight upper labials, fourth and fifth 

 forming the lower edge of orbit ; one elongate temporal shield 

 in contact with both posterior oculars, three or four smaller ones 

 behind. Scales smooth, rhomboidal, in nineteen rows ; anal 

 bifid. Posterior maxillary teeth longest, not grooved, in a con- 

 tinuous row with the remainder. Above brownish olive, with 

 two narrow yellow longitudinal streaks from the occiput to the 

 tip of tail; between the streaks a row of about ninety black 

 cross bars, each formed of two spots ; on the sides a series of 

 similar black cross bars, alternate with the dorsal series ; each 

 of the lateral cross bars provided with two or three yellow specks ; 

 crown of head black ; vertical with two yellow spots behind ; 

 beneath uniform yellowish ; outer edges of some ventral plates 

 black, and forming a lateral series of equidistant spots. Length 

 of cleft of mouth |"; length of the injured tail 2 J" ; length of 

 trunk 18"; length of the restored tail 5". 



V. CORONELLA ELEGANS. 



Lygophis elegans, Tschudi, FaunaPeruana,Herpetol. p. 53. t. 6. 



Scales in fifteen rows ; anal bifid ; eight upper labials, the 

 third, fourth and fifth coming into the orbit. Above olive, with 

 a dorsal series of brown spots, forming on the neck a continuous 

 zigzag line, and on the tail a straight streak ; beneath whitish ; 

 throat minutely black-specked ; on the anterior part a lateral 

 punctated line.
